I am not sure if I catch the issue here. Your expected/actual results are for step 5 or afterwards?

[ghubstan]

The expected/actual results apply to step 5.
When you disable dark mode (5), nothing happens.
It does work after you slide the button back to the left, then slide it to the right a second time.

This issue also exists in Bisq 1.2.3 on Fedora 30.
If dark mode is disabled and Bisq restarted, it comes back in dark mode.
Tried 3 Bisq restarts just now.

If the dark mode button is moved to light mode, and then user goes to any other part of the app, and then returns to Settings, the dark mode selector automatically moves back to dark mode.

So, in my case, not able to turn off dark mode at all yet.
